The Sony SRS-XB43 is a well-built, portable speaker that you can use either horizontally or vertically. It has customizable lighting and an IP67 rating for dust and water resistance that certifies it to be fully dust-tight and immersible in up to a meter of water for 30 minutes. Like many Sony speakers we've tested, it supports ClearAudio+, which is advertised to adjust your speaker's sound field to your audio. Unfortunately, even with its EXTRA BASS and Sony ClearAudio+ features activated, the XB43 has an uneven sound profile that struggles to reproduce a thumpy low-bass. Its soundstage is uneven and narrow, too. However, there's a graphic EQ featured in its Sony Music Center companion app, which you can use to customize its sound to your liking.

Fortunately, you do have some ability to customize its sound to your liking using the graphic EQ in the Sony Music Center app. While it gets loud, its soundstage is narrow, and there's some compression present when you play it at max volume.
